Tucked along the sunny eastern edge of Lake Whatcom sits this exceptional private estate. Comprising 3.1 private acres of flat, usable land, the property features nearly 900 feet of low-bank sandy shoreline—an increasingly rare amount of direct, effortless lake access. The west facing orientation, with unobstructed exposure delivers sunlight from dawn through the long, cinematic sunsets that define life on Lake Whatcom. Three docks and a dedicated boat ramp ensure seamless launch points for whatever vessels or watercraft suit the season, while the generous moorage invites both serious boating and spontaneous summer afternoons. At the heart of the estate are two primary residences. The main home is a refined contemporary with three bedrooms and two-and-a-half baths, designed to frame sweeping 180-degree lake views from nearly every room. Positioned on its own private peninsula, it showcases timeless modern lines with unparalleled potential. Steps away, at the water’s edge, rests the second home—a warmly appointed two-bedroom, two-bath home with loft, perfectly suited for guests or simply changing the daily perspective. Four additional historic cabins complete the offering, one of which has been thoughtfully finished and used as an ADU. Together they create layered possibilities: a true multi-generational compound, thoughtful income potential, or flexible space for a weekend escape. One of a kind would be an understatement for this rare property.
